Abstract: Cationic, cross-linkable acrylic-polyester emulsion binder resin systems are described which are useful as adhesives for binding organic, metal, and glass filaments to each other and to various substrates in the preparation of reinforced composites. These novel binder resin systems are derived from copolymerized ethylenically unsaturated monomers having pendant non-functional, cross-linking functional, and cationic groups. The cationic polymer emulsions are particularly useful when they are cross-linked with polyester resin polymer chains such as those formed by condensing unsaturated dicarboxylic acids with polyols and which can be applied as stable aqueous emulsions.
Abstract: The present disclosure relates to improved polymeric materials and to a process for preparing same, which comprises blending suitable polymers into novel polymeric alloys. The disclosure further relates to novel fire-retarding and flame-resistant materials comprising such polymeric alloys and to novel membrane materials and membranes, adapted to provide novel processes of separation based on membrane technology. The novel polymeric alloys comprise commercially available polymers, blended with novel polymeric phosphonates of the general formula: ##STR1## WHEREIN: M, M', N, N' ARE ZERO OR ANY INTEGER, P IS AN INTEGER HIGHER THAN 10X designates a hydrogen atom halogen atom or a phosphorusContaining groupY designates a CH.sub.2 CHCl or CH.sub.2 CCl.sub.2 groupZ and Z' designates H or a phosphonate group - PO(OR') (OR") (at least one being a phosphonate group), wherein R and R' are alkyl or aryl groups.

Abstract: The disclosure teaches the gelling and thickening of matrix forming resin systems by ion-dipole bonds. Suitable ions are introduced into the resin matrix as alkaline oxides or hydroxides. Thermoplastic polymers containing polar groups are used as additives for the thermosetting resins to offset shrink of the thermosetting resins during their crosslinking and curing in the molding operation. In the molded thermoset state of the resin materials, the polar groups provide sites for the improved bonding of paints, as for example, gel coats. The invention has particular advantages in polyester thermosetting resin systems and in the thermoplastic additives that are used therewith. Polar monomers copolymerized with styrene are the preferred thermoplastic additives.
